Key Takeaways
- The U.S. national debt was more than $31.42 trillion in December 2022.
- The debt-to-GDP ratio gives insight into whether the U.S. has the ability to cover all of its debt.
- Recessions, defense budget growth, and tax cuts have all caused the national debt-to-GDP ratio to rise to record levels.
- The U.S. cannot afford to default on its debt without major global economic consequences.
The U.S. national debt grew to a record $31.42 trillion in by the end of 2022. It has grown over time due to recessions, defense spending, and other programs that added to the debt. The U.S. national debt is so high that it's greater than the annual economic output of the entire country, which is measured as the gross domestic product (GDP).
How To Look at the National Debt by Year
It's best to look at a country's national debt in context. During a recession, expansionary fiscal policy, such as spending and tax cuts, is often used to spur the economy back to health. If it boosts growth enough, it can reduce the debt. A growing economy produces more tax revenues to pay back the debt.
The theory ofsupply-side economicssays the growth from tax cuts is enough to replace the tax revenue lost if the tax rate is above 50% of income. When tax rates are lower, the cuts worsen the national debt without boosting growth enough to replace lost revenue.
Note
Major events, like wars and pandemics, can increase the national debt.
During national threats, the U.S. increases military spending. For example, the U.S. debt grew after theSeptember 11, 2001, attacksas the country increased military spending to launch the War on Terror. Between fiscal years 2001 and 2020, those efforts cost $6.4 trillion, including increases to the Department of Defense and the Veterans Administration.
The national debt by year should be compared to the size of the economy as measured by the gross domestic product. (GDP) That gives you thedebt-to-GDP ratio. That ratio is important because investors worry about default when the debt-to-GDP ratio is greater than 77%—that's the tipping point according to the World Bank.
The World Bank found that if the debt-to-GDP ratio exceeded 77% for an extended period, it slowedeconomic growth. Every percentage point of debt above this level costs the country 0.017 percentage points in economic growth.
You can also use the debt-to-GDP ratio to compare the national debt to other countries. It gives you an idea of how likely the country is to pay back its debt.
Debt by Year, Compared to Nominal GDP and Events
In the table below, the national debt is compared to GDP and influential events since 1929. The debt and GDP are given as of the end of the fourth quarter (unless otherwise noted) in each year to coincide with the end of the fiscal year. That's the best way to accurately determine how spending in each fiscal year contributes to the debt and compare it to economic growth.
From 1947-1976, debt and GDP are given at the end of the second quarter since, during that time, the fiscal year ended on June 30. For years 1929 through 1946, debt is reported at the end of the second quarter, while GDP is reported annually, since quarterly figures are not available.
Note
At the end of the second quarter in 2022, the national debt was about $30.6 trillion. Based on the second-quarter GDP of $24.9 trillion, the debt-to-GDP ratio was about 123%.
